Amazon, apparently caught off guard by the decision, issued the following statement:

Google made a change today at around 3 p.m. YouTube used to be available to our shared customers on Echo Show. As of this afternoon, Google has chosen to no longer make YouTube available on Echo Show, without explanation and without notification to customers. There is no technical reason for that decision, which is disappointing and hurts both of our customers.

Buy an Amazon Echo Show for $200 for a limited time.

Google’s statement instead referenced terms of service violations:

We’ve been in negotiations with Amazon for a long time, working towards an agreement that provides great experiences for customers on both platforms. Amazon’s implementation of YouTube on the Echo Show violates our terms of service, creating a broken user experience. We hope to be able to reach an agreement and resolve these issues soon.

Putting the Echo Show on sale could be an attempt to deal with the lost sales, although Amazon says the two are unrelated.

“The $30 promotion is a limited promotion that was planned well before the removal of YouTube came to light,” an Amazon representative said. “We have circulars that are currently in print and have been since last weekend. As you probably know, it takes weeks to plan, print, work with retailers and get circulars in the hands of customers.”
